|---|---|---|---|---|---|
BioSig Technologies, Inc., along with its subsidiaries, operates as a medical technology enterprise.
Its core innovation is the PURE EP (precise uninterrupted real-time evaluation of electrograms electrophysiology) system. This proprietary signal processing platform, merging specialized hardware and software, tackles well-known difficulties in electrophysiological signal acquisition, empowering electrophysiologists to instantaneously view and analyze vital cardiac signals. The system further enhances the collection of intracardiac signals and diagnostic data crucial for atrial fibrillation procedures. Moreover, it is specifically engineered to overcome persistent obstacles that traditionally slow down and complicate cardiac catheter ablation. BioSig also holds a research agreement with the University of Minnesota, targeting the development of new treatments for sympathetic nervous system disorders.
Additionally, it has a strategic partnership with the Mayo Foundation for Medical Education and Research, focused on creating an advanced AI and machine learning software solution tailored for its PURE EP platforms. Established in 2009, BioSig Technologies, Inc. is headquartered in Westport, Connecticut.
